Abstract: FINGER IDENTIFICATION               Abstract of the Disclosure A finger pressed against a platen provides a finger-print object which is scanned by an interrogating beam of col-limated light in the form of a slit and that is linearly displaced across the platen.  As the slit-beam scans across the back surface of the platen, the reflected light beam is modu-lated.  The modulated beam is imaged onto a linear array of photodiodes to provide a series of output signals indicative of modulation information.  The outputs of the diodes are serially interrogated at each of successive scan positions to provide a set of signals containing fingerprint information.  The platen has a transparent glass base.  A layer of transparent, compres-sible, resilient epoxy is on the back of the glass base.  The epoxy layer has a flat back surface.  A thin silver reflecting layer on the back surface of the epoxy provides a flat mirrored surface to reflect the light beam.  A further epoxy layer on top of the silver provides mechanical filtering.  A lacquer layer at the back protects the platen from wear.  When a finger is applied to the back surface, the ridges of the finger distort the underlying layers sufficiently so that the reflected light at the ridge zones is scattered while the reflected light at the valley zones is collimated.  This difference in scatter is transformed by an imaging lens to a difference in intensity at the diode array.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE       The specification of the present application discloses a casing for a geared hub to be used in transmitting power to the wheel of a vehicle.  The geared hub is particularly useful for all terrain type vehicles where high strength and reliability are required.  The hub uses a one-piece cast housing having various access means to allow assembly of the unit.  The one-piece housing defines an elongated gear chamber which extends generally perpendicular to the wheel spindle.  Three access ports are provided; one for supporting the wheel spindle, a second port for allowing the insertion of an input pinion and input shaft, and a third port for allowing insertion of the output gear.  The first two ports are located in the end walls of the gear chamber with the third port located in the sidewall of the gear chamber.  The unique design, according to the present invention, results in an inherently strong and durable hub having reduced manufacturing and assembly costs.

Abstract: ABSTRACT OF THE DISCLOSURE          In the process of scrubbing flue gas to remove pollutants therefrom by contacting the flue gas with an aqueous reactant mixture of water and pollutant absorbent, water soluble chloride impurities present in the flue gas and make-up water tend to build-up as the supernatant liquor from the spent reactant mixture dewatering cycle is recycled for mixing with unreacted pollutant absorbent to form additional reactant mixture for contacting with the pollutant laden gas.  The build-up of chlorides in the reactant mixture is controlled by passing a purge stream of the chloride containing liquor in contact with a hot drying gas so as to evaporate the water and crystallize the chloride impurities in the purge stream.  The crystallized particles of chloride salt are then removed from the drying gas as a dry solid.

Abstract: ABSTRACT    A new method of forming a composite pre-stressed structural member of the type having an upper molded surface supported by a lower support member is provided.  In this method, a lower support member is connected to the upper side of a mold so that deflection of the mold causes a parallel deflection of the support merger.  With the lower support member connected to the upper side of the mold, support member shear connector means extend downwardly into the mold.  The connected mold and support member are supported so that deflection of the mold and support member can occur.          Following connection of the support member to the mold and supporting them so that deflection can occur, the mold is filled with moldable material which hardens to form a composite structural member with the lower support member.          During hardening of the moldable material, the mold is deflected so that the support member is placed in a stressed condition to form a composite, pre-stressed structural member upon hardening of the moldable material.

Abstract: ABSTRACT A welder having two generally parallel, closely spaced electrodes for manual or automatic welding of wire having displaceable insulation, for use particularly in the wiring of electronic circuit boards. The two electrodes have independent suspensions electrically isolated from one another, and have an aperture formed therebetween sufficiently large to allow a wire to pass therethrough. During the welding process, the wire is captured between the tip of one of the two electrodes and a conductive surface to which the wire is to be welded. As downward force is applied to the welder, the tip of the one electrode displaces the insulation on the wire adjacent thereto and adjacent the surface, while the other electrode tip is driven directly into electrical contact with the surface. Once sufficient force has been applied to the electrode to displace the insulation on the wire, a switch is actuated, supplying a current to the electrodes to weld the wire to the surface. The welder may be either automatically or manually operated, and may utilize either a pneumatic drive or a cable actuation system. The electrodes may be returned to an unactuated position either by a spring arrangement or by a pneumatic cylinder.

Abstract: ABSTRACT: The present invention is concerned with a device for preliminary crushing of a possibly clogged, material to be ground and for feeding of the said material into a jet mill containing a compressed flow of circulating grind-ing gas and material, so as to produce ultra-fineground admixtures to be used in industry.  In prior art, exclusively ejector-type or injector-type feeder de-vices were used as feeder devices of jet mills of the said type, in which feeders the shifting of material into the pressurized mill takes place by means of the grinding gas.  Besides their high energy consumption, another drawback of these prior-art feeder devices consists thereof that the grinding gas jet of the ejector, consisting of water vapour, sucks considerable quantities of air into the jet mill, along with the material, which causes a heterogeneous grind-ing result and makes the recovery of heat after the grinding difficult.  In order to eliminate these drawbacks, a device in accordance with the above inven-tion has been developed, which comprises a substantially vertical so-called plug pipe, which is at its upper end provided with feeder funnel and which is at its bottom end, either directly or via an additional pipe, connected to the jet mill above the zone of the grinding gas nozzle.  At the upper end of the plug pipe, preferably in its feeder funnel, at least one pushing means is pro-vided which moves back and forth and which both crushes any clogged material and forces the crushed material as a tight plug through the pipe into the jet mill.

The apparatus has a charging circuit for charging the battery, a sensing circuit for sensing the state of the battery during charging thereof by the charging circuit and a circuit for determining first and second predetermined reference voltage/-current states.  The apparatus causes the charging of the bat-tery at a preselected initial charging level for an initial time period and establishes a first finish time period.  The apparatus further determines a first time at which the state the battery reaches the first predetermined referenced voltage/current state during the initial time period, and causes the charging circuit to continue to charge the battery at a preselected first charging level after the determination of the first time for a first finish time period.  The appara-tus further establishes a second finish time period and deter-mines a second time at which the state of the battery reaches the second predetermined referenced voltage/current state dur-ing the first finish time period.  The apparatus terminates charging of the battery if the state of the battery does not reach the second predetermined referenced voltage/current state during the first finish time period, and causes the charging circuit to continue to charge the battery at a pre-selected second charging level after the determination of the second time for a second finish time period.
